KST board Jiangsu Zhenjiang steel structure explosion venting board KST roof panel

Description :

　　KST board Jiangsu Zhenjiang steel structure explosion venting board KST roof panel

　　explosion venting

　　Can meet the requirements of special building roofs and walls that are prone to explosion and fragility. Experimental results have shown that the lightweight steel frame of the medium steel frame will be retained on the main structure of the building, while the core material will be instantly crushed, achieving the purpose of explosion venting without causing secondary damage.

　　earthquake resistance

　　：

　　Average sound insulation of the board

　　Above, it meets the sound insulation requirements of high-level acoustic buildings such as studios. Steel skeleton lightweight panels belong to lightweight panels that are conducive to earthquake resistance. With reasonable seismic node design, they can meet the requirements of

　　Requirements for seismic fortification intensity. And during an earthquake, the secondary damage caused by the sheet metal is minimal, making it an ideal component material for buildings in earthquake prone areas.

　　The main materials of the board are natural inorganic materials, which do not release toxic and harmful substances. The board has good breathability and provides a healthy and comfortable living environment. Some industrial waste can be utilized in the production of the board, making it a comprehensive resource utilization product.

　　The installation speed of the board is fast, with fewer construction steps, greatly shortening the construction period; The shape and specifications of the board can be customized according to customer requirements, which can meet the needs of opening holes, hanging objects, and other usage requirements; The board provides a convenient and reasonable solution for supporting construction such as skylights, fan equipment, lightning protection systems, and secondary decoration.

　　8.1 The main ribs of the lightweight steel frame plate shall be sandblasted for rust removal, and the surface of the steel main ribs shall be thoroughly rust removed, with a rust removal grade of St3. If rust is found during use, measures should be taken in a timely manner. The connection between the steel main rib and the end rib, as well as the stiffening rib, is welded with a welding foot size of 4mm full

　　Welding, the welding quality complies with the relevant current national standards.

　　8. Welded steel wire mesh is used inside the lightweight steel frame slab, with short span small b Sa} 150 as the lower reinforcement, and the length extending into the support shall not be less than SOmm; Long span b 3 secret 200 is the upper reinforcement, which extends into the support for a length of not less than 30mm, and is welded one at a distance from the edge ribs unless otherwise specified.

　　8.3 The suspension rod of the steel skeleton lightweight board ceiling should be connected to the edge ribs and should not be connected to the core board.

　　When stacking lightweight plates with a steel skeleton of 8.4 SB, the height of each stack should not exceed 10 pieces, and wooden pads should be placed flat and aligned vertically. During loading and transportation, the overhanging length of the board should not exceed 300mm.

　　When lifting the lightweight steel skeleton plate with a size of 8.5 GD, a special lifting device should be used to lift at four points, with no more than two pieces lifted at a time.

　　8.6 Steel skeleton lightweight panels can only be shipped when the core material strength reaches 950/of the design strength. SB steel lightweight composite panels should be prevented from friction and collision during transportation and installation. Any paint peeling or local damage caused by friction or collision should be repaired in a timely manner.
